I think this is because peptide hormones are made in advance and stored in secretory vesicles while steroid hormones are synthesized on demand on precursors, thus the response of peptide hormones will be more rapid. Additionally the receptors for peptides are on the cell membrane while those for steroid hormones are located on cytoplasm or nucleus, some have receptors on the membrane also.

Regulation of heart rate, blood pressure, and digestive functions are carried out by the ______________________.

Regulation of heart rate, blood pressure, and digestive functions are carried out by the <u>autonomic nervous system</u>

What is autonomic nervous system?

The peripheral nervous system's autonomic nervous system (ANS), originally known as the vegetative nervous system (VNS), provides smooth muscle and glands, which in turn affects how internal organs work. The autonomic nervous system is a control system that regulates body processes like the heart rate, digestion, respiratory rate, pupillary response, and urination mainly subconsciously. The fundamental mechanism in charge of the fight-or-flight response is this system.

Through the brainstem, the spinal cord, and the organs, integrated reflexes control the autonomic nervous system. Control of respiration, cardiac regulation (the cardiac control center), vasomotor activity (the vasomotor center), and other reflex acts including coughing, sneezing, swallowing, and vomiting are all examples of autonomic functions.

Answer: c. proteasome

Explanation:

Proteasomes are extremely important multi-catalytic proteases and are involved in various cellular functions. The proteasome is an essential component of eukaryotic cells and is responsible for the ATP-dependent proteolytic degradation of most cellular proteins. They are present in the nucleus and cytosol and can represent up to 1% of total cell proteins. Proteasomes generally degrade proteins to small peptides, most of which are rapidly hydrolyzed by cytoplasmic exopeptidases. It catalyzes the rapid degradation of many enzymes, regulatory proteins, and eliminates abnormal proteins resulting from mutation or damaged proteins. The inability of this cellular organelle can lead to neurodegenerative diseases, such as Parkinson´s disease.
